2.4 Using a 10 mm drill, drill 70 mm deep holes to accept the wall plugs, and insert wall plugs. 2.5 Fit the mounting jig assembly using the four fixing screws provided (Ensure that all the service cocks are in the OFF position). Operate valves several times to ensure they are free. 2.6 With the exception of the connection to the pressure relief valve, make all the water and gas connections to the jig bracket valves. Fully tighten (fig. 11). Water connections can be made with compression or capillary fittings (before the gas inlet to the boiler there must be at least 100 mm of straight before any bends). 3.0 FIXING THE MOUNTING JIG ON THE WALL (Side Wall Flue Applications) 3.1 Select the boiler location carefully ensuring that all the requirements given in previous text are satisfied. Fig. 10 will aso give guidance. 3.2 Locate the template on wall and mark the position of the four jig bracket fixing holes. 3.3 Using a 10 mm drill, drill 70 mm deep holes to accept the wall plugs, and insert wall plugs. 3.4 Fit the mounting jig assembly using the four fixing screws provided. 3.5 Extend a horizontal line from the centre of the rear flue outlet to the side wall. 3.6 Mark the centre line (vertically) for the flue assembly hole, and mark the centre of the hole. 3.7 Carefully cut the circular hole (118 mm minimum diameter) for the flue assembly. 1001 Important Note -Always use two spanners to prevent twisting of soft copper pipework on the boiler. Flush out the water system. Note -The maximum inlet cold water pressure must not exceed 10 bar (145 P.S.I.) and a water governor or a pressure reducing valve will be required if the pressure is in excess of 5 bar (72 P.S.I.). Ensure all pipework is adequately supported.

Aluminium flue pipe length = Plastic air inlet pipe length plus 70 mm longer. K = 4.1.1 Accurately measure the Wall thickness (P1) 4.1.2 From the end opposite to the terminal, cut the plastic air duct (dimension A1) to length (P1 + 192 mm). Note -That the terminal is not included in A1. 4.1.3 Cut the aluminium flue duct to length (P1 + 262 mm) (dimensions F1). Note -The aluminium flue pipe must be 70 mm longer than the plastic air inlet pipe. 4.1.4 Drill a 3 mm hole 15 mm from the plain end of plastic air duct. 4.1.5 Place flue components to one side to be used later.

Important -The aluminium flue pipe must protrude into the outside grill by 60 mm, never cut it to the same length as the plastic air pipe. Aluminium flue pipe length = Plastic air inlet pipe length plus 70 mm longer. 4.2.1 Accurately measure the Wall thickness (P2). 4.2.2 Accurately measure the distance from the centre of the stud fixing of the mounting jig assembly to the side wall (Q2). 4.2.3 From the end opposite to the terminal, cut the plastic air duct (dimension A2) to length (P2 + Q2 + 180 mm). Note -That the terminal is not included in length A2. 4.2.4 Cut the aluminium flue duct to length (P2 + Q2 + 250 mm) (dimension F2). Note -The aluminium flue pipe must be 70 mm longer than the plastic air inlet pipe. 4.2.5 Drill a 3 mm hole 15 mm from the plain end of plastic air duct. 4.2.6 Place flue components to one side to be used later. 1001 5.0 CONNECTING THE BOILER 5.1 Place the boiler on its back. 5.2 Remove the boiler base plate, four screws (fig. 16). Remove the plugs fitted to the boiler water connections. Remove the bag of sealing washers from the boiler pipework. Remove the front panel by gripping on both sides, sliding up and pulling away from the main boiler. 5.3 Lift boiler as shown in fig. 15 onto the top studs and fit supplied nuts and washers hand tight. 5.4 Lift at bottom to engage the water and gas connections. Tighten central heating flow and return, and the domestic hot water inlet and outlet, using appropriate sealing w...
